This study assessed the validity of health insurance information on California birth certificates.
Insurance information from birth certificates and linked face-to-face interviews was compared for 7428 postpartum women in California.
There was excellent agreement between insurance information in birth certificate and interview data, especially when capitated plans were grouped with all other private coverage. Analyses using both data sources produced similar estimates of the likelihood of untimely prenatal care according to type of insurance coverage.
Birth certificate data including insurance information appear to be an appropriate resource for examining both the extent of coverage for maternity care and associations between prenatal care use and insurance status.
本研究评估了加利福尼亚州出生证明上医疗保险信息的有效性。
对加利福尼亚州7428名产后妇女的出生证明保险信息与面对面访谈的相关信息进行了比较。
出生证明中的保险信息与访谈数据之间具有高度一致性,尤其是将按人头付费计划与所有其他私人保险合并统计时。使用这两种数据源进行的分析得出了根据保险覆盖类型划分的产前护理不及时可能性的相似估计值。
包含保险信息的出生证明数据似乎是用于研究孕产妇护理覆盖范围以及产前护理使用与保险状况之间关联的合适资源。
